Ingredients for Chicken Breast with Mustard Sauce

These quality ingredients create a restaurant-worthy dish with minimal effort and maximum flavor impact.

The chicken quality is paramount here. Boneless, skinless breasts from a reputable butcher or Whole Foods ensure tender results. Pounding to even thickness (about 3/4-inch) prevents dry edges while centers cook through. For the mustards, Maille or Grey Poupon offer consistent quality and flavor balance. The wine should be dry and crisp—Sauvignon Blanc is ideal, but any drinkable white works.

No white wine? Substitute chicken broth with 1 tbsp lemon juice. Shallots can be replaced with finely diced onion (use 2 tbsp). If avoiding alcohol, apple cider vinegar (1 tbsp) plus broth works. For a lighter sauce, half-and-half instead of heavy cream still delivers good body. The thyme and parsley are flexible—tarragon or chives add nice variation.

Store raw chicken on a plate on the bottom fridge shelf (use within 2 days). The sauce keeps 3-4 days refrigerated but is best fresh. Reheat gently to avoid separating the cream. Leftover chicken makes great sandwiches or salads for up to 3 days.

Step-by-Step Instructions for Chicken Breast With Mustard Sauce

Here’s the tested method for achieving tender chicken with a rich, velvety mustard sauce.

Step 1: Pound and Season the Chicken Breasts

Place the 1.5 lb Boneless Skinless Chicken Breasts between two sheets of plastic wrap. Pound them to an even ½-inch thickness using a meat mallet. This ensures even cooking and prevents dry spots in thicker areas.

Season both sides generously with 1 tsp Kosher Salt and 0.5 tsp Black Pepper. Then dredge each piece in the 0.25 cup All-Purpose Flour, shaking off any excess. The flour creates a light crust that helps thicken the sauce later.

Step 2: Sear the Chicken to Golden Perfection

Heat 1 tbsp Olive Oil in a large skillet over medium-high heat until shimmering. Add the floured chicken and cook for 4-5 minutes per side until golden brown and just cooked through. The internal temperature should reach 165°F.

Don’t move the chicken during the first 2-3 minutes—this allows a proper sear to develop. Transfer the cooked chicken to a plate and tent with foil to keep warm. The residual heat will finish cooking the chicken while you prepare the sauce.

Step 3: Build the Flavor Base for the Sauce

In the same skillet, reduce heat to medium and add the remaining 1 tbsp Olive Oil and 2 tbsp Unsalted Butter. Once the butter melts, add the finely minced 1 whole Shallot and cook for 2-3 minutes until soft and translucent.

Add the minced 2 cloves Garlic Cloves and cook for 30 seconds until fragrant. Be careful not to let the garlic burn—it should turn golden, not brown.

Step 4: Deglaze and Create the Creamy Mustard Sauce

Pour in the 0.5 cup Dry White Wine and scrape up all the browned bits from the bottom of the pan with a wooden spoon. Let the wine simmer for 2-3 minutes until reduced by half.

Stir in the 0.5 cup Chicken Broth, 2 tbsp Dijon Mustard, and 1 tbsp Whole Grain Mustard. Simmer for 2 minutes until slightly thickened. Then reduce heat to low and whisk in the 0.25 cup Heavy Cream until smooth and creamy.

Step 5: Finish and Serve

Return the chicken to the skillet along with any accumulated juices. Spoon the sauce over the chicken and let it simmer for 1-2 minutes to heat through and meld flavors. Taste and adjust seasoning if needed.

Garnish with 1 tsp Fresh Thyme Leaves and 2 tbsp Fresh Parsley before serving. The sauce should coat the chicken with a glossy finish, delivering a perfect balance of tangy and creamy in every bite.

Perfect Pairings for This Recipe

Wine Pairings

A crisp Sauvignon Blanc like New Zealand’s Kim Crawford complements the tangy mustard sauce beautifully. Its bright acidity cuts through the creaminess while enhancing the dish’s zesty notes.

Beer Options

A light Belgian-style witbier such as Hoegaarden offers citrus and spice that pair well with the mustard. For a darker choice, a German pilsner delivers crisp refreshment without overpowering the flavors. 🍺

Side Dishes

Roasted asparagus with lemon zest adds a fresh, bright contrast to the richness. Simply toss 1 lb asparagus with olive oil, salt, and roast at 400°F for 12-15 minutes.

Starch Pairings

Garlic mashed potatoes soak up the creamy sauce perfectly. Boil 2 lbs Yukon Gold potatoes, mash with ½ cup warm milk and 4 tbsp butter, then stir in roasted garlic cloves for depth.

Bread Options

A crusty baguette or sourdough is ideal for mopping up every last drop of sauce. Warm slices in the oven at 350°F for 5-7 minutes to restore freshness. 💛

Vegetable Additions

Steamed green beans with almonds add texture and color. Blanch 1 lb green beans for 2-3 minutes, then toss with toasted slivered almonds and a squeeze of lemon.
